Application filed February 26, 1916. Serial No. 80,559.

coal, ballast, etc., and wherein the operating mechanismfor the doors iscomposed of few parts and so arranged that thesame may be convenientlyoperated; to provide a novel arrangement of center sill constructionwhereby the latter is materially strengthened; and in general to soarrange the va rious parts and devices as to provide a more efficientand economical car than, those heretofore in use.

In the drawing forming a part of this specification,- Figure 1 is a sideelevation of a car showing my improvements in connection therewith. Fig.2 is a part top plan and part horizontal section of the car illustratedin Fig. 1, and showing more particularly the arrangement of dooroperating mechanisms. And Figs. 3 and 4 are detail, transverse sectionalviews taken respectively on the lines 3-3 and 44 of Fig. 2. And Fig. 5is a detail section of a portion of the center sills, illustrating moreparticularly the sheaves for the chains and the method of mounting thecross shaft on the lower faces of the center sills.

In said drawing, the car body is represented as having side walls 10,inclined end walls 11, a boxlike built-up center'sill 12 formedpreferably of channels, and four extending longitudinally of hoppers AAside of the center sill the car, two on each thereof. car at the centerthereof is a sheet 13 having a centrally located ridge 14, vertical portions 1515 secured to the sides of the center sill, and outwardly anddownwardly inclined lower portions 16-16, the latter portions forminglongitudinal hopper sheets for the hoppers A. The outer, inwardly anddownwardly inclined sides of the hoppers in the county of Cook and Stateof Extending longitudinally of the are formed by longitudinal hoppersheets 17-17, which are secured at their upper edges to the side wallsof the car. Extending transversely of the car at the center thereof andbridging the space between the adjacent ends of the hoppers, is asubstantially inverted V shaped sheet 18 and beneath which are locatedthe auxiliary operating shafts as hereinafter described.

Referring now more particularly to Figs. 3 and 4, it-will be seen thateach hopper A is provided with a center dumping door 19 and a sidedumping door 20, said doors having flanged lower edges as indicated at21, which abut each other and form a closure when the doors are inclosed position. The center dumping doors 19 are each hinged along theirupper edges to three hinge butts 22 disposed beneath the outwardlyinclined further brace the construction at this point plates 24 areprovided having vertical portions riveted to the center sills andoutwardly and upwardly inclined portions riveted to the tops of theangle irons 23. With the arrangement of longitudinal sheet 13 and themembers for hinging the center dump doors, it will be seen that thecenter sill is greatly strengthened against buffing shocks which mighttend to buckle the center sill. In addition, the hinge butts for thecenter dump doors are out of the way of the load and the longitudinalsheet 13 forms a good shedding surface to facilitate unloading the car.The side dumping doors 20 are also hinged along their upper edges tohinge butts 240 located beneath the hopper sheets 17, there being angleirons 25 interposed between the butts and the sheets 17 to provideadditional stren against longitudinal stresses. Located beneath themeeting edges of each set of hopper doors is a divert-ing shelf 26having a ridge or apex along its upper surface whereby the load isdeflected to either side of the rail, depending upon'which set of-doorsis operated.

It is desirable to operate the side dumping doors simultaneously andalso the center dumping doors simultaneously. For this purpose I haveprovided three longitudinally extending operating shafts 27, 28 and 29.The center shaft 28 is located beneath the center sill and is mountedwithin suitable 65. ends of the two shafts,

bearing brackets 3030, see Fig. 1, secured to said sill. The shafts 27and 29 are mounted in suitable bearing castings 3131 which are securedon the inner faces of depending plates 32, 33 and 34, secured to thesides of the car. Between the shaft 28 and all of the side dumping doors20-20 are flexible link connections, each consisting of a hook shapedlink 35, short link 36, link 37 and arm 38 formed integrally with a drummounted on said shaft, the linkages being so arranged that the shaftwillbe self locked when the doors are in closed position, that is, therewill be no tendency of the shaft to be rotated when the "car is loadedand weight is on the doors. For operating the shaft 28, I haveprovided amanually operated, auxiliary shaft 39 which extends from the. center ofthe car transversely to one side thereof. ()n this shaft 39 are twowinding drums 40 and 41 over which wind chains 42,wsaid chains at theirlower ends also winding over corresponding drums 43 and 44 secured tothe shaft 28. The drums 40, 41, 43 and 44 and chains 42 are so connectedthat as the shaft 39 is rotated in one direction the side dumpingdoorswill be opened and when the shaft 39 is rotatedin the oppositedirection, the doors will be moved to closed position. Similar flexiblelink connections are provided between the longitudinal shafts 27 and 29and the nearest set of hinged center dumping doors 19. In order that theshafts 27 and 29 may be operated simultaneously I have provided atransversely extending auxiliary shaft 45 having worms 145 thereon whichcooperate with worm gears 46 on each of said shafts 27 and 29. Theauxiliary shaft 45 is extended to one side of the car where it isadapted to be operated by any suitable means such as the pawl andratchet arrangement indicated diagrammatically in Fig. 1. By means ofthe worm and worm gear connections just described, it is'apparent thatnot only will the doors 19 be operated simultaneously but that thelatter may be held in any desired adjusted position, thereby adaptingthe car particularly for ballast service where itis desired to dump theballast between the rails.

It will be noted that the transversely extending auxiliary shafts 39 and45 are not only located centrally of the car but also centrally of therespective longitudinal shafts with which they cooperate so that inrotating the shafts 27, 28 and 29 torsion on the latter is minimized.Furthermore, by locating the two transverse shafts 39 and 45 in the samespace beneath the transverse hopper sheet 181the' arrangement is compactand on one side of the car, see the upper portion of Fig; 2, I andenabled to use one depending side plate 'for supporting the outer),

Although I have herein shown and described what I now consider thepreferred embodiment of my invention, the same is merely descriptive andI contemplate all 'on each side of the center sill, each hopper having apair of door openings, oppositely swinging doors for each pair ofopenings thus forming "four longitudinally arranged sets of doors,longitudinally extendingdirerting partitions at the bottoms of saidhoppers, and two sets ofindependently operable mechanisms forcontrolling said four sets of doors, one of said mechanisms includ ingone longitudinally extending shaft and the other mechanism including twolongitudinally extending shafts.
